Thermal tympanic thermometer tip
View Patent ↗A method for reducing temperature measurement error in a tympanic thermometer. The present disclosure provides a tympanic thermometer including a heat sensing probe defining a longitudinal axis and an outer surface extending from a distal end of the tympanic thermometer. The heat sensing probe includes a thermally insulating sensor housing extending to a distal end thereof. Can-packaged temperature sensing electronics are mounted at the distal portion of the sensor housing. A thermally conductive nozzle is configured to direct heat flux to the temperature sensing electronics in the distal end of the heat sensing probe. The sensor can preferably include a lip extending radially therefrom and contacting the nozzle at at least one contact point to provide heat flux to the sensor can.
1. A method of assembling a tympanic thermometer comprising:
providing a heat sensing probe including a thermally insulating sensor housing; forming the sensor housing from a thermally insulating material;
mounting a sensor can on the thermally insulating sensor housing, the sensor can including temperature sensing electronics for sensing temperature via the heat sensing probe;
mounting a thermally conductive nozzle onto the thermally insulating sensor housing, said nozzle including a thermal conductive base and an elongated cylindrical nose portion; and
configuring the nozzle, sensor can and housing to direct heat flux from the distal end of the sensor can to a proximal end of said sensor can and to reduce the temperature gradient from a can tip to a sensor base.
2. The method according to claim 1 further comprising contacting said thermally conductive nozzle at least one contact point with a lip extending radially from the sensor can to provide heat flux to said sensor can.
